Get priceTo go from 212F water to low pressure steam requires another 970 BTUs per pound. Increasing the pressure increases the temperature of the phase change, and increases the amount of energy the water/steam can carry. At pressures higher than atmospheric, more heat must be added to water (sensible heat) before it can turn to steam.
